python - 重新启动游戏和用户输入无效时，回合#计数器不会重置

Question

所以我不明白为什么当我重新启动游戏时我的计数器没有重置，而且我相信这与我没有构建器的事实有关？任何帮助都将受到高度评价！

当您RPS.game()在函数本身内调用时会出现问题。这会产生一种情况，即所有变量都会按照函数的定义进行重置.game()。为避免这种情况，您可以为函数提供默认参数，然后使用这些参数调用函数（在其内部）。

示例（使用部分原始代码）：

def game(player=0, rounds=0):

    # player = 0
    # rounds = 0
    moves = ['Rock', 'Paper', 'Scissors',]
    r = rundnum

    while rounds < r:
        rounds += 1
        comp = random.choice(moves)

        print(colored("Choose : ", 'green'), colored("1)Rock", 'red'), colored("2)Paper", 'yellow'),
              colored("3)Scissors", 'grey'))

        try:
            player = int(input("What's Your Guess? "))
        except:
            print(colored("No Valid Input! Restarting Game...", 'red'))
            RPS.game(player, rounds) # Here's the magic...
